as organocatalysts in the three-component cycloaddition of CO2, propargyl alcohol and primary amine was investigated, and 2,2′,2″-Terpyridine was found to be the efficient organocatalyst to afford 4-methylene-2-oxazolidinones or 2(3H)-oxazolones in good to high yields. 2,2′,2″-Terpyridine also showed high catalytic activity in the coupling reaction of CO2 with aziridines bearing either electron-donating
研究了吡啶在CO 2,炔丙醇和伯胺的三组分环加成反应中作为有机催化剂的催化活化作用,发现2,2',2''-三联吡啶是提供4-亚甲基-2-亚甲基-2-吡咯烷酮的有效有机催化剂。恶唑烷酮或2(3 H)-恶唑酮,收率高至高。2,2',2''-三联吡啶在CO 2与带有给电子或吸电子N-取代基的氮丙啶偶联反应中也显示出高催化活性,从而以高收率得到取代的2-恶唑烷酮。
